Toyobo Celanex® 2401MT® ECO-B PBT
Categories: Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT); Polybutylene Terephthalate (PBT), Unreinforced, Molded

Material Notes: Product Description: Celanex 2401MT ECO-B is unfilled, medium flow PBT grade for injection molding processing. Celanex 2401MT ECO-B is a special grade developed for medical industry applications and complies with: CFR 21 (177.1660) of the Food and Drug Administration (FDA), and is listed in the Drug Master File (DMF 10047 (US)/10033 (EU)) and the Device Master File (MFA 443 (US)/1078 (EU)) the corresponding EU and national registry regulatory requirements biocompatibility corresponding to USP 23 Class VI/ISO 10993 low residual monomers contains no animal products Celances ECO-B is a PBT with the same properties and performance as standard grades, but produced with sustainability in mind. Using a mass-balance approach, max 40% of biogenic feedstocks are used to offset the use of fossil-based raw materials and decrease greenhouse gas emissions. The process will be audited and certified according to the REDcert mass balance approach.
